## Abstract Arylnitroso compounds **1β3** easily reacted with dimethyl bromomalonate to give the corresponding __N__βarylβ__C,C__βdimethoxycarbonylnitrones (**4β6**). Treatment of __C,C__βdimethoxycarbonylβ__N__β( 1βnaphthyl)nitrone (**4**) with acetylene compounds (dimethyl acetylenedicarboxylate,
Under microwave irradiation, perbenzylated pyranoid glycals were coupled with aryl bromides in the presence of 5% mol palladium(II) acetate in dimethylformamide to produce 2 0 ,3 0 -unsaturated C-aryl-aglycopyranosides in a rapid and stereospecific manner. The synthetic applicability of the method w
